Pollen is released and carried by the wind to female cones.

On maturity, the female cones detach and fall to the ground.

As with flowers, seeds form within the female cone after pollination.

The main differences between the two are in the number, size and form of the male and female cones.

Female cones are stalked or sessile, erect, and have short hairs.

It is Plant sexuality, with male and female cones on separate plants, which are wind pollinated.

The familiar woody cone is the female cone, which produces seeds.

The male and female cones are borne separately on the same tree; pollination is in early spring.
